With the global population expected to top 7 billion people in 2011, National Geographic magazine has produced a 7-part year-long series providing a profile of the world’s population. The information is fascinating, and from a design point of view, it shows the effective graphic use of the magazine’s yellow and black brand colors and yellow rectangular frame logo, which has been around since the magazine began publishing in 1888. From a marketing strategy perspective, it gives us a lot to think about.
